Preventing scrapie, a transmissible spongiform encephalopathy affecting sheep and goats, involves implementing strict biosecurity measures. These include sourcing animals from scrapie-free flocks, maintaining good herd health management practices, and regularly monitoring and testing for the disease. Additionally, culling infected or at-risk animals and avoiding the use of potentially contaminated feed can help reduce the risk of transmission. Proper disposal of carcasses and contaminated materials is also crucial in preventing the spread of scrapie.
In the US, scrapie has caused certain bloodlines to be disfavored and discontinued due to the genetic susceptibility to scrapie. In addition, flocks are monitored for the presence of scrapie and if a scrapie problem is detected the flock may be depopulated (destroyed) or the lambs have to be carefully raised by hand to get the infectious protein out of the flock.

They get BSE or Kuru or Scrapie.
because it looked like a scratch
Goats and sheep can get scrapie, a transmissable spongiform encephalopathy (TSE). Other animals can get TSE's but they are called different names eg Mad Cow Disease etc
Prions.
there are none

Transmissible Spongiform Encephalopathy: Scrapie in sheep and Mad Cow disease (or Bovine Spongiform Encephalopathy)
Scrapie is transmitted among sheep and goats through ingestion of contaminated feed or placental tissues, or through direct contact with infected animals or their bodily fluids. It is believed to be caused by an abnormal protein called a prion that can be shed in bodily fluids and tissues of infected animals.
Mad Cow Disease and Scrapie are NOT caused by incomplete viruses or any virus of any sort. They are caused by PRIONS, which are misfolded proteins much tinier than any virus, complete or not. If such disease were caused by viruses they would easily be cured by an antibiotic, but since they are not caused by bacteria or a virus, such vaccines cannot be made because there is nothing for such a vaccine to target.
